Description

Technical Field

[0001] The present invention relates to the field of outdoor units of air-conditioning equipment, and in particular to an outdoor unit and an air conditioner. Background Art

[0002] With economic development, the use of air conditioners is becoming increasingly common. Air conditioners typically consist of indoor and outdoor units, with the latter comprising a top cover, front panel, and side panels. The top cover of a top-discharge multi-split outdoor unit not only mates with the fan blades but also with surrounding sheet metal components such as the side panels and front panel, making it difficult to achieve a complete seal. Furthermore, since outdoor units are typically placed outdoors, water can accumulate and become difficult to drain during rainy days. Therefore, rainwater must be drained from the top cover to prevent corrosion. However, indiscriminate drainage can seriously affect the lifespan and safety of the air conditioner.

[0003] The prior art with publication number CN207622164U discloses an outdoor unit top cover and an outdoor unit housing. The outdoor unit top cover includes a profile having alternating convex and concave surfaces. Drain holes are provided in the concave surfaces to prevent accelerated corrosion after water accumulation. However, the drainage holes on the profile allow rainwater to flow into the unit, which will seriously affect the service life of the air conditioner. Summary of the Invention

[0004] In view of this, the present invention aims to propose an outdoor unit to solve the problems in the prior art that water accumulation on the top cover plate accelerates corrosion and rainwater enters the unit through the top cover plate, affecting the service life of the air conditioner.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] An outdoor unit includes a top cover and side panels. The short sides of the top cover are connected to the side panels. An upwardly folded edge is provided on the long sides of the top cover. A first water channel is provided near the folded edge. A second water channel is provided on the side panels. The first water channel and the second water channel are connected. Rainwater on the top cover is drained outside the unit, effectively preventing unsafe conditions caused by rainwater entering the unit.

[0007] Furthermore, the first water channel is arranged at the edge of the long side of the top cover plate and the first water channel is arranged as a groove, so as to drain rainwater on the top cover plate to the four corners through the groove.

[0008] Furthermore, a plurality of profiles are provided on the top cover plate, and the profiles are connected with the first water channel to fully ensure that rainwater can be discharged from the profiles, thereby preventing accelerated corrosion of the top cover plate.

[0009] Furthermore, any profile on the front side of the top cover plate is connected to the first water channel on the front side, and any profile on the rear side is connected to the first water channel on the rear side, with the purpose of draining rainwater on any profile to the first water channel to prevent water accumulation in the profile and accelerating corrosion of the top cover plate.

[0010] Furthermore, a first flange, a second flange, and a third flange are provided at the long sides of the side panel, the side panel is connected to the first flange, the first flange is connected to the second flange, and the second flange is connected to the third flange. The connection between the first flange and the side panel increases the strength and sealing of the frame, the second flange is used for the rainwater drainage channel to prevent rainwater from entering the unit, and the third flange is used to increase the strength and sealing of the frame and can also prevent rainwater from the second flange from entering the unit.

[0011] Furthermore, the second water channel is located on the second flange, and rainwater is drained out of the unit through the second water channel of the side plate.

[0012] Furthermore, the second water channel is configured as a groove for draining rainwater.

[0013] An outdoor unit further includes an upper enclosure plate, wherein the upper enclosure plate is provided with a notch and a fourth flange, and the notch is located at the upper end of the fourth flange.

[0014] Furthermore, the fourth flange is connected to the third flange, with the purpose of connecting the side panels and the upper enclosure panel to increase the strength and sealing of the frame.

[0015] Compared with the prior art, the outdoor unit of the present invention has the following advantages:

[0016] 1) By providing a folded edge and a first water channel on the top cover plate, and a second water channel on the side plate, the first water channel and the second water channel are connected. Rainwater at the two folded edges of the top cover plate is drained through the first water channel to the second water channel, and then drained out of the unit, thus fully eliminating the hidden danger of rainwater entering the unit on rainy days and endangering the safety of the unit;

[0017] 2) By designing the profiles on the top cover to be connected, and the profiles to the folds to be connected, on the one hand, it is ensured that there is no water accumulation in any profile to prevent corrosion of the top cover, and on the other hand, rainwater in the profile is drained out of the unit to avoid any unsafe factors for the unit;

[0018] 3) A first flange, a second flange, and a third flange are provided on the long sides of the side panels, which not only increase the strength and sealing of the frame, but also set the second flange into a groove for rainwater drainage. The third flange is set perpendicular to the second flange to prevent rainwater in the groove from entering the unit.

[0019] The present invention also provides an air conditioner, comprising the outdoor unit described above.

[0020] The advantages of the air conditioner and the outdoor unit described above over the prior art are the same and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] like Figure 1-7 As shown, an outdoor unit includes a guide ring 5 and a frame. The frame includes: a top cover plate 1, side panels 2, an upper enclosure plate 3, and a base 4. The top cover plate 1 is arranged on the top of the outdoor unit to form the top appearance of the outdoor unit. The two long sides of the top cover plate 1 are connected to the upper enclosure plate 3, and the two short sides of the top cover plate 1 are connected to the side panels 2, and the side panels 2 are arranged on the outside of the base 4. The guide ring 5 is located in the frame and close to the lower end of the top cover plate 1.

[0041] In addition, a pair of air outlets 13 are formed on the top cover 1 so that the air that has undergone heat exchange inside the outdoor unit can be blown out to the outside of the outdoor unit.

[0042] Although a small amount of rainwater has little effect on a general outdoor unit, the top-outlet multi-split unit has a complex internal structure. Even if a small amount of rainwater enters the unit, it will have a certain impact on the outdoor unit. Therefore, upward folding edges 11 are provided at the edges of the two long sides of the top cover plate 1. The folding edges 11 are tightly fitted with the upper panel 3 and extend to the four corners of the top cover plate 1. The folding edges 11 can play a role in drainage.

[0043] A first water channel 12 is provided near the folded edge 11 to drain rainwater through the folded edge to the first water channel 12. Specifically, the first water channel 12 is close to the long edge of the top cover 1 and is configured as a groove. The first water channel 12 extends to the four corners, facilitating drainage of accumulated water on the top cover to the four corners. The first water channel 12 serves as a channel for rainwater drainage, effectively preventing rainwater on the top cover from entering the unit, thereby extending the service life of the outdoor unit.

[0044] The guide ring 5 is located at the lower end of the top cover plate 1. In addition to being used to accelerate the airflow therein, it can also be used to prevent rainwater from entering the unit.

[0045] Specifically, if Figure 6-7 As shown, when there is rainwater on the top cover plate 1, the rainwater can be discharged at the four corners through the drainage effect of the two long side folds 11. At the same time, because there is a guide ring 5 under the top cover plate 1, due to the blocking effect of the guide ring 5, the rainwater cannot enter the unit, but flows out from the outer wall of the guide ring 5, thereby effectively preventing rainwater from entering the interior of the unit and ensuring the safety of the unit.

[0046] The top cover plate 1 may further be provided with a drainage portion 14 . The drainage portion 14 is located on both sides of the air outlet 13 and close to the folded edge 11 of the top cover plate 1 .

[0047] The drainage portion 14 includes a plurality of profiles. Specifically, the plurality of profiles include a first profile 141 , a second profile 142 , a third profile 143 , a fourth profile 144 , a fifth profile 145 , and a sixth profile 146 .

[0048] Preferably, the first pressure profile 141 , the second pressure profile 142 , the third pressure profile 143 , the fourth pressure profile 144 and the sixth pressure profile 146 are respectively arranged at the four corners of the top cover plate 1 , and the second pressure profile 142 and the fifth pressure profile 145 are located in the middle of a pair of air outlets 13 .

[0049] Each profile is preferably a closed annular structure, with a concave and convex surface. A drainage hole 15 is provided on the concave surface. The lower portion of the drainage hole 15 corresponds to the arc curve of the guide ring 5. When there is a lot of rain, water will accumulate on either profile, accelerating the corrosion of the top cover 1 and threatening the normal operation of the unit. Therefore, when rainwater enters, it can flow out through the drainage hole 15, achieving the drainage effect.

[0050] Specifically, when rainwater enters the folded edge of the top cover plate, the rainwater is drained to the four corners of the top cover plate through the first water channel through the drainage effect of the folded edge, and is blocked by the guide ring to prevent rainwater from entering the unit. When rainwater enters the press-fit part of the top cover plate, the rainwater is discharged through the drainage holes in the press-fit, which can prevent rainwater from corroding the top cover plate. In addition, the rainwater flows down from the drainage hole through the arc curve of the guide ring, and is blocked by the arc curve of the guide ring to prevent rainwater from entering the unit. The rainwater will be drained to the corners of the outdoor unit along the arc curve of the guide ring, so that the rainwater will not enter the inside of the unit, thereby extending the service life of the outdoor unit.

[0051] As part of embodiment 1 of the present invention, an air conditioner is also provided, comprising the outdoor unit described above.

[0052] Example 2

[0053] like Figure 8-15 As shown, in addition to the outdoor unit and air conditioner of Example 1, the outdoor unit of this embodiment also includes a plurality of pressure profiles of the drainage portion 14 designed to be connected. Specifically, the first pressure profile 141, the second pressure profile 142, and the third pressure profile 144 are in the connected state in sequence. Similarly, the fourth pressure profile 144, the fifth pressure profile 145, and the sixth pressure profile 146 are in the connected state in sequence, and the second pressure profile 142 and the fifth pressure profile 145 are in the connected state.

[0054] The multiple profiles on the top cover plate 1 are connected to the first water channel. Specifically, any profile on the front side of the top cover plate 1 is connected to the first water channel on the front side of the top cover plate. Similarly, any profile on the rear side of the top cover plate is connected to the first water channel on the rear side of the top cover plate. Specifically, the first profile 141, the second profile 142, and the third profile 143 are connected to the first water channel 12 closest to them, and the fourth profile 144, the fifth profile 145, and the sixth profile 146 are connected to the first water channel 12 closest to them. The purpose is to drain the water in any profile to the first water channel 12, so that rainwater can be discharged from the first water channel 12, thereby preventing rainwater from staying on the top cover plate 1 for a long time, causing corrosion of the top cover plate 1 and threatening the normal operation of the unit.

[0055] The long side edges of the side panel 2 are provided with a first flange 21 , a second flange 22 and a third flange 23 . The side panel 2 is connected to the first flange 21 , the first flange 21 is connected to the second flange 22 , and the second flange 22 is connected to the third flange 23 .

[0056] Specifically, along the center direction of the outdoor unit frame, the side panel 2 is connected to one side of the first flange 21, the other side of the first flange 21 and away from the side panel 2 is connected to one side of the second flange 22, and the other side of the second flange 22 and away from the first flange is connected to the third flange 23. Preferably, the first flange 21 and the third flange 23 are arranged in parallel, and the first flange 21 is perpendicular to the second flange 22.

[0057] A second water channel 221 is provided on the second flange 22, and the second water channel 221 is perpendicular to the ground. The provision of the first flange, the second flange and the third flange not only increases the strength of the frame, but also increases the sealing performance of the connection with the upper enclosure. The most important thing is that a channel for draining rainwater is added to the second flange, and the third flange 23 is perpendicular to the second flange 22, which can effectively prevent rainwater on the second water channel 221 from entering the unit.

[0058] The second water channel 221 is in communication with the first water channel 12. Preferably, the second water channel 221 is perpendicular to the first water channel 12. The purpose of providing the second water channel 221 is to guide rainwater from the top cover plate 1 to the side plate 2.

[0059] The side panels 2 are connected to the outside of the base 4 so that rainwater can be drained to the outside of the base through the second water channel 221, thereby preventing the top air outlet from entering the air conditioner due to excessive rainwater, which could cause unsafe conditions.

[0060] Preferably, the second water channel 221 is a groove, and the groove is recessed along the surface where the second flange 22 is located and close to the first flange 21 .

[0061] Preferably, a slot 231 is provided on the third flange 23 .

[0062] The upper enclosure 3 is provided with a notch 31 and a fourth flange 32. The fourth flange 32 is provided on the short side of the upper enclosure 3 and is connected to the third flange 23 of the side panel 2. The notch 31 is located at the upper end of the second flange 22. The notch 31 is used to extend the first water channel 12 so that the first water channel 12 is connected to the second water channel 221. In this way, rainwater can pass through the notch 31 of the upper enclosure 3 from the first water channel to reach the second water channel 221 of the side panel 2. Rainwater flowing out of the second water channel 221 will not affect the safety of the unit.

[0063] A buckle 321 is provided on the fourth flange 32 , and the buckle 321 corresponds to the slot 231 of the third flange 23 .

[0064] Specifically, when rainwater enters the folded edge of the top cover, the drainage function of the folded edge allows the rainwater to flow from the first water channel through the notch of the upper panel and into the second water channel of the side panel. The rainwater is then drained downward along the second water channel to the outside of the base, preventing rainwater from entering the unit and extending the service life of the outdoor unit. When rainwater enters the profile of the top cover, the connecting channel between the profiles is used to drain the rainwater to the first water channel connected to the profile, preventing water accumulation in the profile from corroding the top cover. In addition, the rainwater flows through the first water channel through the notch of the upper panel and into the second water channel of the side panel. The rainwater then flows out of the base along the second water channel, preventing rainwater from entering the unit and extending the service life of the outdoor unit.

[0065] As part of embodiment 2 of the present invention, an air conditioner is also provided, comprising the outdoor unit described above.

[0066] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
